Definitions

  • the invention relates to an actuating unit for motor vehicle applications, in particular motor vehicle door locks, with a drive, and with a linear actuator which can be acted upon by the drive.
  • Such actuators are used by way of example and not limitation as Zuziehosvoriques, as presented inter alia in DE 101 12 120 B4.
  • the Zuziehosvorraum works on the trunk lid of a motor vehicle.
  • an electric motor is provided which operates on a linear actuator.
  • the electric motor has a flanged gearbox and is placed either in or on the boot lid.
  • the problem often arises in practice that the electric motor is not aligned correctly during assembly relative to the linear actuator and / or has play. This can cause vibrations during operation.
  • the control unit in question is mostly used to act on motor vehicle door locks or even entire motor vehicle doors, these elements often act as resonators or can act in this way.
  • the operation of the known actuators is often associated with disturbing noises.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of further developing such an adjustment unit for applications in the automotive industry so that the background noise is improved overall.
  • the invention proposes in a generic actuator, that the drive and the linear actuator
  • CONFIRMATION COPY Angled in particular at right angles, are or are arranged to each other. In this way, any noise from the drive is not or hardly transmitted to the opposite angle arranged linear actuator. Because the angular and in particular right-angled arrangement of on the one hand the drive and on the other hand the linear actuator means as a rule that the drive and the linear actuator are coupled together via a worm gear. Such a worm gear is relatively insensitive, as regards any vibrations. Even a possible game in the drive is usually mastered easily. In any case, the background noise of the actuator according to the invention over previous embodiments is significantly improved in this way.
  • the drive and the actuator are regularly taken together stored in a housing. This procedure also improves the noise behavior. Because the housing is used for encapsulation on the one hand the drive and on the other hand the actuator, so that a noise emission to the outside is reliably suppressed. In addition, any structure-borne noise transmission due to the angled arrangement of the drive on one side and the linear actuator on the other is considerably reduced, if not completely suppressed, compared to previous embodiments.
  • the drive is coupled to the housing via at least one bearing point.
  • two bearing points are used, so that the drive is connected to the housing via a two-point bearing with the aid of the two bearing points. It has proven to be particularly advantageous if the respective bearing is designed as a press bearing seat.
  • Such a press bearing seat is usually equipped with webs, which are regularly deformed in the course of assembly of the drive in the housing.
  • the webs are mostly rib squeezing.
  • the bearing can be made in several parts or in one piece. Either way, the assembly of the drive with the help of one or more press-bearing seats that the drive is properly aligned with respect to the linear actuator and the other that the drive permanently free of play in the housing undergoes a holder.
  • the bearing is usually formed in the housing.
  • the bearing point can also be performed on the drive.
  • the bearing can be defined on a separate bearing sleeve, in and / or on the respective bearing sleeve.
  • the bearing is made partly of a plastically easily deformable material such as plastic, preferably in the form of crush ribs.
  • Plastic easily deformable means in this context a material which is deformed or deformed during the (manual) assembly of the drive. This can be done, for example, that the drive is placed in the housing and when it is fixed in the housing, the bearing or the press fit learns the desired fully or partially deformation.
  • the housing may be made in two or more parts. As a rule, one will fall back on a cover part and a top part. So as soon as the drive is placed in the housing, it comes to the described deformation of the bearing.
  • the drive is generally received in the upper part.
  • the invention expressly allows an orientation of the drive relative to the housing and / or relative to the linear actuator in certain and given by the respective press bearing seat limits. After the drive or electric motor has taken the desired orientation this is maintained throughout the operation, because the associated bearing has partially plastically deformed. This is essentially ensured by the crush ribs or the webs realized at this point. As a result, the drive is held without play in the housing. Vibrations almost do not occur (anymore).
  • the drive or electric motor can be fixed with low tolerances and without play and taking into account the possibility of its alignment with respect to the housing and the linear actuator. This is of particular importance for a good and especially quiet engine running.
  • the invention proposes according to a further advantageous embodiment, that the drive in addition to the at least one press bearing seat as a bearing bearing a rubber bearing seat as a further bearing point.
  • the rubber bearing seat is formed in a rubber ring that absorbs the drive completely or partially. This rubber ring is used regularly to accommodate and enclose a bottom of the electric motor.
  • a press bearing seat may be provided at the end of an output shaft of the electric motor.
  • Another press bearing seat may be provided in the region of a collar, which has a passage opening of the The output shaft encloses by a motor housing. Of course this is not mandatory.
  • the respective press bearing seat or the pinch ribs can be formed directly in the housing, which - like the press bearing seat - is regularly made of plastic. But it is also possible to define the press bearing seat or generally the bearing point in or on a separate bearing sleeve.
  • the bearing sleeve is advantageously made of plastic.
  • such a bearing sleeve may be plugged onto the output shaft on the head side. With the help of this bearing sleeve then the drive respectively the thus equipped electric motor can be placed in the associated storage tub.
  • the bearing sleeve engages with the usually outside crush ribs or associated webs in a bearing sleeve receiving opening.
  • the crush ribs deform and ensure proper mounting and mounting of the output shaft in the example case.
  • This procedure can be realized particularly advantageous in that the drive is rotationally symmetrical and, moreover, the bearing points can be formed as associated ring or partial ring sleeves.
  • an actuator for automotive applications which is characterized by a particularly quiet operation.
  • This low-noise operation can essentially be attributed to the fact that the drive or the electric motor used regularly at this point is placed in a housing and in relation to the associated linear actuator, taking into account at most slight tolerances.
  • the rotational movement made available by the drive on its output shaft is transmitted to the linear actuator in a perfect, precise and low-vibration manner.
  • This may be a spindle nut drive, which of course is to be understood only as an example and not restrictive.
  • an actuator for motor vehicle technical applications fertilize shown.
  • automotive applications it is not restrictive essentially to parking functions in conjunction with one or more vehicle door locks 1.
  • the illustrated actuator may be used to apply a Zuzieh raised in such a motor vehicle door lock 1, as described for example in DE 101 12 120 B4 is described. This is of course only to be understood as illustrative and not restrictive.
  • the linear actuator 3, 4 is in detail a spindle drive with a threaded spindle 3 and mounted in the housing 8b by means of ball bearings or plain bearing spindle nut 4, which is to be understood only as an example and not limiting.
  • the drive or electric motor 2 has an output shaft 5.
  • the output shaft 5 transmits its rotational movements via a worm gear 6 to the linear actuator 3, 4 and the spindle nut 4.
  • the stationary mounted spindle nut 4 is rotated and moves the mounted on the spindle nut 4 spindle or threaded spindle 3 depending on their Direction of rotation back and forth, as indicated by a double arrow in the figure.
  • a connected to the spindle 3 Bowden cable or a comparable connecting element now transmits these linear actuating movements of the linear actuator 3, 4 on the motor vehicle door lock 1 in the example case.
  • the drive or electric motor 2 on the one hand and the linear actuator 3, 4 on the other hand are arranged at an angle to each other.
  • the output shaft 5 of the drive or electric motor 2 and, on the other hand, the threaded spindle 3 describe a right angle ⁇ to each other.
  • the threaded spindle 3 describe a right angle ⁇ to each other.
  • the rotational movements of the output shaft 5 can already be precise and low-vibration transmitted to the linear actuator 3, 4.
  • the circumstance contributes to the fact that the drive or electric motor 2 is coupled via two bearing points 7, T to a housing 8b.
  • the housing 8a, 8b is made in two parts and consists in the core of a cover part 8a and a top 8b together.

  • the respective bearings 7, 7 ' are made in the example of plastic.
  • the bearing T is in two parts or generally designed in several parts and is defined in an opening 8b of the housing.
  • the press bearing seat 7 'receives a collar 10 of the engine mount of the drive 2 inside.
  • This collar 10 is formed in the region of a housing of the drive or electric motor 2, in which the output shaft 5 leaves the housing in question. That is, the collar 10 surrounds an outlet opening of the output shaft 5 of the drive 2 from the associated housing.
  • the further bearing 7 or the press bearing seat 7 is formed in the exemplary embodiment on a bearing sleeve 7. In this bearing sleeve 7 is a separate component for supporting the drive 2, which - like the housing 8a, 8b - is made of plastic.
  • the bearing sleeve in question 7 is inserted during assembly of the drive 2 in an associated bearing bush 11 of the housing 8b.
  • the bearing sleeve 7 has been plugged onto the output shaft 5.
  • the bearing sleeve 7 acts as a plain bearing bush, which receives the head-side end of the output shaft 5.
  • the housing 8a, 8b is designed as an injection molded part made of plastic. Also in the bearing sleeve 7 is an injection molded part made of plastic. In this way it is ensured that the webs or crush ribs 12 undergo the described plastic deformation during assembly of the drive 2 and the union of the drive 2 with the housing 8b surrounding it and the bearing points. Because the interpretation is generally chosen so that the webs or crush ribs 12 from their combined diameter ago (slightly) are sized larger than an associated diameter of the press bearing seat 7,7 'or the combined openings, which surround the collar 10.
